"Survey of Music Technology" is a new massive open online course available at Coursera (https://www.coursera.org/learn/music-technology). This course provides a hands-on introduction to the field of music technology as both a creative musical practice and an interdisciplinary technical research pursuit. Students will be able to compose music in digital audio workstation software using both audio and symbolic representations; to write code to algorithmically generate music, analyze sound, and design sound; and to describe the essential theory and history behind these activities as well as their connection to cutting-edge computer music research. Through the exploration of topics such as acoustics, psychoacoustics, digital sound, digital signal processing, audio synthesis, spectral analysis, algorithmic composition, and music information retrieval, we will explore the deep relationships between art and science, between theory and practice, and between experimental and popular electronic music. It is offered by Prof. Jason Freeman (http://distributedmusic.gatech.edu/jason/). This course seems as an interesting application of signal processing to music.
